1. RYB-8 Relay Board

1.1 Introduction

The MCN-RYB-8 board is a relay board accessory to the MCN Monitoring and
Control Network product family.

The MCN-RYB-8 board has the following features:

• (8) DPDT Relays (Configured to switch circuit pairs).

• Hi-reliability long-life sealed relays.

• Relays rated for low-level (dry circuit) audio switching, up to 2A.

• Selectable 600 Ohm terminations for the Normally Open, Normally Closed, or

Common circuits (may be de-selected).

• LEDs to indicate which relays are active.

• Control Connector (relay coil inputs) which is pin-compatible with the MCN

IOB modules.

• 25-pair telco connectors used for control inputs and relay outputs.

• Jumpers to control adjacent relays.

• Jumpers for Sub-Category strapping for MCNRCD variable status text

messages.

• Optional EIA 19” rack-mount panel available for mounting (4) MCN-RYB-8

boards.

Part Number Description
S3-60644 Basic board with no jumpers installed
S2-60694 Board with standard jumpers installed
E1-E8: B1 installed (I/O Line 1 controls relays)
B4 installed (Spare sub-category jumper, parked)
E9-E16: (2) jumpers installed in park position
(600 Ohm Termination de-selected)
S2-60508 Board with A/C jumpers installed
S2-60509 Board with B jumpers installed
S2-60510 Board with C/C jumpers installed
S2-60794 Board with A/B jumpers installed
S2-60645 Cable Assy, IOB/CIB/IIB to RYB-8, 50 Conductor, 1' Length

Note: The MCN RYB-8 Relay board is pin-compatible with the IOB module and
is fully supported for operation with it. Although it is also pin- compatible with
the CIB Comparator Interface Module (in Spectra-TAC mode only), it is not
supported for use with CIB modules. References are made within this document
to the CIB Comparator Interface Module only for completeness, especially with
the MCNRCD PC Software.

1.2 Circuit Description

The MCN-RYB-8 board has 8 identical circuits. The following will describe the
first such circuit.

Relay K1 has the following I/O bits associated with it:

Pin

21 1 1 Input/Output VOTE 1 Input/Output 1
22 1 2 Output RECEIVE 1 input 1
20 1 3 Input/Output DISABLE 1 Input/Output 9
23 1 4 Output FAIL 1 input 9

Relay I/O Bit Relay Board

CIB Module

IOB Mode 1

Signal

I/O bits 1 or 3 can be used as inputs to drive the coil of the relay (see Figure 1).

Each relay has its own jumper block (E1-E8) to select the input that will drive the
relay coil. Each relay can be controlled from either I/O bit 1 or 3 associated with
it, depending upon the position of the B1 or B3 jumper in jumper blocks E1-E8.
The following table shows the jumper configuration for relay K1:

J2 Pin I/O Bit Jumper

21 1 E1-B1 In (Default)
20 3 E1-B3 In

Only one jumper (E1-B1 or E1-B3) should be installed at a time.

1.2.2 Sub-Category Jumpers E1-E8 “A” Side

When you use the MCN Relay Board with an MCN IOB module and the
MCNRCD PC Software, you can use the “A” side of jumper blocks E1 through
E8 to provide static sub-category status text selections. This will allow you to
specify different status text messages (On/Off, Up/Down, Main/Standby, etc. as
defined in the MCNRCD.CFG file) for different relays on the MCN-RYB-8
board.

For relay K1, the jumpering is shown in Table 1:

J2

Pin

21 1 1 E1-A1 In VOTE 1 Input/Output 1 1
22 1 2 E1-A2 In RECEIVE 1 input 1 04
20 1 3 E1-A3 In DISABLE 1 Input/Output 9 10
23 1 4 E1-A4 In FAIL 1 input 9 40

Bit Weight

Table 1 - Sub-Category Jumpers

Since I/O bit 1 is normally used to control the relay, I/O bits 2-4 are available for
sub-category selection. Up to (8) sub-categories can be configured with these 3
bits. When a jumper is inserted, the bit is active. See the MCNRCD Software
Manual and IOB hardware manual for more details on sub-categories.

1.2.3 Adjacent Relay Drive Jumpers E17-E23

In some applications you may need to drive two relays from the same input
signal. You can use jumpers E17-E23 to connect a relay's coil to an adjacent
relay's coil.

E17 jumpers the coils for relays 1 & 2 together. E18 jumpers relays 2 & 3, and so
on.

When you insert the Adjacent Relay Drive jumpers (E17-E23), be sure that you
have only one input active (E1-E8 "B" side) for each set of relays that are
connected together.

These jumpers are normally not installed from the factory, unless a custom
configuration is ordered.
